Abstract
In a guide roller for web material with two outer tube sections (2, 2a) and optionally with at least one tube section 1 that is arranged between these, the tube sections (1; 2; 2a) are supported through ball bearings (5; 7) on a central shaft 3. The outer tube sections (2; 2a) are radially adjustable relative to the shaft 3 at their outer ends. The ball bearings (7) that support the outer tube sections (2; 2a) are arranged on a sleeve (20) that surrounds the shaft (3) and is spaced apart therefrom, this being supported on the shaft (3) at its end that faces the centre of the guide roller, and is radially adjustable by a threaded spindle (4, 4') that fits in an outer threaded area (13a; 13a') that faces radially towards the middle of the shaft. At the front end, the threaded spindle (4; 4') rests on a peripheral surface of the shaft (3) or sleeve (20) or on a supporting surface (11) that is arranged concentrically to this. The outer threaded area (13a) is arranged within a carrier (13) that is supported on the sleeve (20) or on the shaft (3). The carrier (13) is twistable about the shaft (3) and can be locked in different twisted positions.
Description
Guide Roller for Web Material TECHNICAL DOMAIN
The present invention relates to a guide roller for web material.
PRIOR ART
In a known guide roller of this type (DE 196 22 238 Cl), the outer tube section is adjusted by a threaded spindle that is screwed into a threaded section that passes transversely through the shaft of the guide roller. A sleeve is secured to the projecting ends of the threaded spindle, and this is supported on the shaft by its end that faces the centre of the guide roller. Rotating the threaded spindle causes the sleeve to twist, and thereby twists the outer tube sections that are supported on the sleeve. The sleeve can only be twisted in the direction of the threaded shaft, which is to say, radially.
THE INVENTION
It is the objective of the present invention to render the inclination of the outermost tube sections adjustable with respect to direction, which is to say in a tangential direction.
According to an aspect of the invention, there is provided a guide roller for web material with two outer tube sections, the outer tube sections being supported through first ball bearings on a central shaft, and the outer ends of the outer tube sections being radially adjustable relative to the shaft, each of the outer tube sections having a sleeve, the first ball bearings being arranged on the sleeve, the sleeve surrounding the shaft and being spaced apart from the shaft, the sleeve being supported on the shaft at a sleeve end that faces the centre of the guide roller, and which is radially adjustable by a threaded spindle that fits in an outer threaded area and faces radially towards the middle of the shaft, wherein the front end the of the threaded spindle rests on a peripheral surface of the shaft, or sleeve or on a spindle supporting surface that is arranged concentrically to the shaft; and wherein the outer threaded area is arranged within a carrier that is supported on the sleeve or on the shaft, and wherein the carrier is twistable about the shaft and fixable in different twisted positions.
la The directional adjustability of the inclination of the outer tube sections renders adjustment of the guidance of the web material particularly precise.
BRIEF DESCRIPTION OF THE DRAWINGS
Two preferred embodiments of the present invention are described in detail below on the basis of drawings appended hereto. These drawings show the following:
Figure 1: A first embodiment of a guide roller in partial longitudinal cross section;
Figure 2: A partial representation of a second embodiment, in partial longitudinal cross section.
BEST WAY TO IMPLEMENT THE INVENTION
In the drawings, identical parts bear identical reference numbers. Should it be necessary, these are distinguished from each other by apostrophes appended to the numbers.
An inner tube section 1 is supported on a shaft 3 by a ball bearing 5 that is accommodated by a bearing bushing 9. The outer tube sections 2, 2a are secured to the inner tube section 1 through couplings 12 so as to be rotate in unison and are supported on a sleeve 20 through ball bearing 7. The ball bearing 7 is secured on the sleeve 20 with a bearing sleeve 21.
The inner end of the sleeve 20 rests on the shaft 3 through an 0-ring 15. In the embodiment shown in Figure 1, a sleeve-shaped pressure ring 17 is releasably secured on an area 3b of the shaft 3, said area 3b being of reduced diameter, the pressure ring 17 being screwed to an element through which the threaded spindle 4 passes and which is in the form of a supporting ring 10. The outer peripheral surface of the pressure ring 10 acts as a supporting surface 11 for the threaded spindles 4, 8. A clamping ring 6 provides security in the axial direction.
An area 4b of the threaded spindle 4, which is of lo greater diameter, lies in a recess that is formed as a retaining area on the inner side of the supporting ring 10. The threaded area 4a of the threaded spindle 4 is screwed into the outer threaded area 13a of a carrier 13 that is configured as a ring that is arranged so as to be fixed on the sleeve 20. The threaded spindle 8 is arranged in the carrier 13 so as to be aligned with the threaded spindle 4 on the side that is opposite on the shaft 3.
Adjustment of the threaded spindle 4 shifts the sleeve and thereby the outer tube section 2 radially relative to the 20 shaft 3. The direction of inclination of the sleeve 20 that has been set is secured with the threaded spindle 8. Once the threaded spindle 8 has been loosened, the direction of inclination is determined by the rotation of the supporting ring 10 by the carrier 13, which takes place jointly with the threaded spindle 4 and the sleeve 20.
In the second embodiment as shown in Figure 2, the threaded spindle 4' is supported in the outer threaded area 13a', in a carrier 13 that is in the form of a bell housing, A guide pin 14 passes through the carrier 13' on the side that is opposite the threaded spindle 4'. The threaded spindle 4' lies on the supporting surface 11' of the sleeve 20.
At its end that faces the shaft and has a threaded extension, the guide pin 14 is screwed into a retaining ring 18 that encloses the sleeve 20. On its inner side, the retaining ring 18 has a recess that forms a retaining are for the area 4b that is of increased diameter. The carrier 131 is releasably secured to the that shaft 3 by the lock screw 16. It is additionally fixed in the axial direction by a clamping ring 6'.
The direction of inclination of the sleeve is fixed by rotating the carrier 13' once the lock screw 16 has been loosened.
The present invention relates to a guide roller for web material.
